LOOSE-LEAF BJINJDER.

Maronti.

To all whom t may concern:

' Bev it known that I, JOHN SCHADE, a citizenv of Vthe United States, residing at Holyoke, Hampden county, State of Massachusetts, have invented certain new and useful improvements inLoose-Leaf Binders;-

a'n'd l dodeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art toV which it appertains to make and usethe same.

' This invention relates to certain details in connection with the manufacture of loose leaf binders and more particularly those of the' transfer type which employ covers secured` to barstthe` invention being a special form, and pattern of metal cap which is designed `to coverthe tubes at the ends to present ank artistic appearance, at the Same time reinforcing the tube, securing a construction which is cheap to, manufacture, handsome in appearance andv capable of withstanding hard use. The invention also provides a novel means of securing the cap to the tube.

ln'the drawings Fignre 1 is a fragmentary top elevation of a binder having the present invention incorporatedtherein; 1

Fig. 2 is a sectional view on line 2-2 of Fig. 1; l Fig. v3 is a similar view on line' 3 3 of Fig. 2;

Fig. 4: is a detailed elevation of the end cap showing the preferred form of vthe invention;

Fig. 5 is an end elevation thereof;

Fig. 6 is a` side elevation of a slightly modified embodiment of the invention; and Fig. 7 is an end elevation thereof.

Referring more particularly to the drawing, the numeral 1 designates the top bar of a top or end lock binder of that type embodying a base and spaced upstan'ding posts which pass through perforations 2 in said top bar, the latter being hingedly connected to the cover section 3 by the fabric, as at 4.

The top bar is preferably formed from a piece of sheet metal bent into a flattened tubular casing, the edges of which are free as depicted in Fig. 3. Adjacent each end of Specification of Letters Patent. Y Pgmigmibngdl July 2, 11h91,

Appncatin filed my 17,1917. semaine.181,060.1 i

this casing is provided a pair of openings 5, y

terior surface which presents a neat'finish f for the bar. In the preferred'form the cap has depending end walls 7 which extend inwardly over and embrace the exterior of the bar 1, the intermediate side wallsbeing vinturned to form abutments or shoulders 9 and are then extended in parallel .relation fromthe cap body into the end of the bar 1, as at 10. Arlhe side wallsl() have locking spurs 11 lanced or struck `out therefrom, the same extending outwardly toward the cap body and possessing sufficient resiliency'to spring into theopenings; 5 for interlocking with the top bar. The side walls preferably extend from one end portion only of the body so as not to interfere with the internal mechanism not shown, a hey-hole `12"`being provided in the opposite endportion of the cap body for access to the latter.

ln operation, the fabric covering 13 for the top bar isv slightlyextended` beyond the latter and turned'inwardly and theend cap positioned onthe bar so that the Spurs interlock in the openings 5, the shoulders 9 engagingtheturned'over edge `of the fabric covering to securely clamp the same against the end of the bar.

In the modification, a reversal of theparts is provided in which the end walls llfare lill inturned to form shoulders land arelanced 1 toprovide the locking spurs 16, the side walls 17 extending overthe exterior` ofthe bar to embrace the fabric covering.

or seamless tubing formerly used because y of the stiening or reinforcing capacity of the end caps in that the latter embrace the exterior of the 'casing to prevent expansion v capA design whereby it engages the tube both inside l and loutside, thus preventing it' from collapsing or expanding.

What is claimed is: A;gl.- [n. z L loose leaf binder, a bar comprising agflattrenedrtubular: casing having openings inlfijts upperandl lower Vvvvalls and adjacent one end, a fabric covering for the bar eX- tended'over said .end thereof, and a sheet metalvendapcut andstamped to form a body 4,havinga pair of opposing and depend-Y ing wallsextending inwardly over and embracing theouter surface lof the fabric covering, and a second .pair of opposing walls inturned to;r provide shoulders and. extended downwardly insideV the casing, said second walls havingfspurs stamped therefrom to interlockin the casing openings for holding theyrend cap onrthevbar 'and the shoulders z'rgainstfthe ndofthe bar to clamp the fabric-'@Overng-z r f Inca' bar forloose leaf'binders, a casing bentfrom sheet metal into tubular form and,y provided withV- opposing openings adjacent V-an end, a fabric covering for the casinghaving its end inturned over the end of the' casing, and an end cap V.having means einbracingboth thev interior andexterior of the casing for securing the fabric thereto. In `aba-r for loosehleaf binders, a casing bentjfrom sheet metal into tubularform and provided with opposing openings adjacentan -.end,a yfabric ,covering for the casinguhavingits end inturnedrover the end of the casing @andan end cap having opposing wallsfdnturnedgto kprovide shoulders for clamping the fabric against the end of the casing and means von the walls forfinterlockigviin the casing openings to secure the end4v cap in place. Y; Y f i In; a bar 4for loose leafbinders, Aa casing bent from sheet metal into tubular form and provided with opposing openings adjacent an end, an end cap having opposing walls inturncd to provide shoulders which set snugly against the end of the casing and spurs struck out from the walls for interlocking with the casing openings.

5; In a bar for loose leaf binders, a casing bent from sheet metal into tubular form and provided with opposing openings adjacent an end, a fabric covering for the casing having its end inturned over the end of the casing, and an end vcap having opposing Walls inturned to provide shoulders for clamping the fabric against the end of the casing and spurs struckout from the walls for interlocking with the casing openings, said cap also having interposed and opposing walls embracing the exterior of the casing and its fabric covering.

6. An end cap for the bars of a transfer binder comprising a body having opposing walls formed with struck out spurs and being outturned above the latter to form abutment shoulders.`

7. An end cap for the bars of a transfer binder tube comprising a body having opposing walls formed with struck out spurs and-ibeing'outturned above the latter to form abutment shoulders, and spaced opposing walls interposed between the others for embracing theexterior of a top bar.

8.. In a loose leaf binder, a bar comprising a flattened tubular casing open at the ends, an end cap having opposing projections inturned to provide shoulders which fit snugly against the ends of the casing, while the projections themselves lie against the inner surface of the casing, said cap also having oppositely disposed parts Which lie against the outer sides of the casing, and means v for securing said projections to the casing. A In testimony whereof I aix my signature.
